Hi,
The tableless layout for the manual is here: http://www.php.net/manual/en/tableless/index.php It displays quite fine in Mozilla & Firefox, but is problematic in IE, since it does not interpret the float model correctly. I would be happy to see patches for this though :)) I definitely expect this to be fixed, and that livedocs should use this layout.
If the only problems are that there is a horizontal scrollbar and Prev and Next sections don't have margins, here is my proposal:
1. Don't float .manualnavbar at right. 2. Swap the order of .prev and .next, and .langchooser and .langupdated and don't float .prev and .langchooser at left. 3. Don't clear .manualnavbar HR. 4. Remove .cleaner from .manualnavbar.
This style is also simpler in my eyes. Tested with IE 6 and Opera 7.23. I hope it works in other browsers too but I didn't test it.
I have applied your patch. It will turn out if it breaks something else (like Mozilla browsers :).
